Static analysis was failing with:
hidpassthrough\hidpassthrough.c(109): warning C28169: The dispatch function 'HidPassthroughDispatchIoctl' does not have any _Dispatch_type_ annotations: This can be corrected by adding appropriate _Dispatch_type_ annotations to the function. Unnecessary casts can cause this warning.
sys\device.c(271): warning C28170: The function 'VIOInputCreateChildPdo' has been declared to be in a paged segment, but neither PAGED_CODE nor PAGED_CODE_LOCKED was found: This warning is not emitted for functions that are __forceinline.
sys\driver.c(88): warning C28208: Function VIOInputEvtDriverContextCleanup was previously defined with a different parameter list at c:\kvm-guest-drivers-windows\vioinput\sys\driver.c(38). Some analysis tools will yield incorrect results.
sys\driver.c(91): warning C28118: The current function is permitted to run at an IRQ level above the maximum permitted for '__PREfastPagedCode' (1). Prior function calls or annotation are inconsistent with use of that function: The current function may need _IRQL_requires_max_, or it may be that the limit is set by some prior call. Maximum legal IRQL was last set to 2 at line 90.

The driver can now build an HID report descriptor describing
controls from the consumer HID usage page. These usually come
in the form of special keyboard keys (volume up/down, launch
www browser, calculator, etc.)
